GENERAL INFORMATION
ORGANISM
UNIPROT
COMMENTARY hide
LITERATURE
malfunction
metabolism
-
the main change in the Escherichia coli fatty acid composition when CsFatA is expressed is the reduction in unsaturated fatty acids, mainly cis-vaccenic acid (18:1 omega7). This reduction is compensated for by an increase of palmitoleic acid (16:1 omega7); the main change in the Escherichia coli fatty acid composition when CsFatB is expressed is a decrease in saturated fatty acids and in particular, that of palmitic acid (16:0) that is compensated for with an increase in stearic acid (18.0)
physiological function
-
deduced amino acid sequence displays high homology to choroplastic palmitoyl-acyl carrier protein thioesterases from other plants

Q215W
-
mutant displays equivalent or improved activities towards all substrates with marked 2 and 2.6fold increased activities for palmitoleoyl-ACP and palmitoyl-ACP, respectively, compared to wild-type. Expression of mutant in Nicotiana benthamiana leads to a higher average values of acyl-CoA. Expressed in Arabidopsis mutant displays displays a 40% decrease in oil content relative to wild-type. Mutant produces an increase in the content of saturated fatty acids, palmitic and stearic acids, with a concomitant decrease in oleic acid derivatives
